1. A vacuum attachment for reaching smaller spaces, the attachment comprisinga. a gasket comprisingi. a cap member sized to fit over an open end of a vacuum hose, the cap member having an inner surface and a central hole to accommodate a narrow tube;
- ii. an inner wall extending from the central hole of the cap and gripping the narrow tube; and
iii. an outer wall extending from the cap member to a distal edge and accommodating the vacuum hose;
iv. a middle wall between the inner and outer walls, the middle wall stiffening the gasket for more convenient operation and accommodating an additional size of vacuum hose, the outer and middle walls being equipped with ribs on the internal sides of the walls, the ribs extending from the cap to the distal ends of the walls; and
v. the cap member inner surface having a plurality of ridges that extend radially from the inner wall to the middle wall, the ridges being so designed as to let air pass and reduce pressure build up in a vacuum motor; and
b. at least one narrow, bendable tube fashioned to fit into the central hole of the cap member and having sufficiently thick walls to avoid collapse when a vacuum is applied thereto.

Abstract
A vacuum attachment for reaching smaller spaces includes a gasket and narrow tubing. The gasket has a cap with outer and middle walls sized to fit an open end of two sizes of vacuum hose, the cap also having a central hole for the narrow tube. The gasket middle wall also stiffens the gasket. On the internal sides of the walls, the ribs stiffen the gasket and ridges let air pass and reduce pressure build up in a vacuum motor. The narrow, bendable tube has sufficiently thick walls to avoid collapse when a vacuum is applied thereto.

12. A vacuum attachment for reaching smaller spaces, the attachment comprising
a. a gasket comprising i. a cap sized to fit over an open end of a vacuum hose, the cap member having a top surface and a central hole to accommodate a narrow tube, the top surface having at least one hole to relieve pressure; -
ii. an inner wall extending from the central hole of the cap and gripping the narrow tube; iii. an outer wall extending from the cap member and accommodating the vacuum hose; iv. a middle wall between the inner and outer walls, the middle wall stiffening the gasket for more convenient operation and accommodating an additional size of vacuum hose, the outer and middle walls being equipped with ribs on the internal sides of the walls, the ribs extending from the cap to the distal ends of the walls; and v. the cap member inner surface having a plurality of ridges that extend radially from the inner wall to the middle wall, the ridges being so designed as to let air pass and reduce pressure build up in a vacuum motor; and b. at least one narrow, bendable tube fashioned to fit into the central hole of the cap member and having sufficiently thick walls to avoid collapse when a vacuum is applied thereto. - View Dependent Claims (13, 14, 15, 16, 17, 18)
